Mica and PTFE Capacitors

Mica and PTFE capacitors have been fundamental components of electronic circuits for many decades. Despite their age and relative lack of design advances, they remain essential devices in a variety of applications. The CMR06F911FODP is a member of this family, and its properties, applications, and working principle are described in detail below.

The CMR06F911FODP Mica and PTFE Capacitor

The CMR06F911FODP is a small, cylindrical, surface-mounted capacitor consisting of a core of molded plastic which encloses a disk of mica impregnated with PTFE (polytetrafluoroethylene). The core size is 6.3mm x 2.5mm, and the capacitor has an overall diameter of 6.9mm and an overall length of 11mm. The CMR06F911FODP has a rated capacitance of 0.0009 μF, a voltage rating of 500V, an insulation resistance of > 5x109 ohms, and a dissipation factor of 0.0002. It is designed to operate over a temperature range of -40°C to +85°C.

The Working Principle of Mica and PTFE Capacitors

Mica and PTFE capacitors operate on the same principle as other types of electrical capacitors. They consist of two or more conductive plates separated by an insulating material; in this case, mica impregnated with PTFE. An electric field is created between the plates, and this field stores an electrical charge until the circuit is disrupted. When the circuit is connected, the electric field produces a current which can be used by the device.

Applications of the CMR06F911FODP Capacitor

Due to its small size and high voltage rating, the CMR06F911FODP capacitor is suitable for a range of high-frequency applications in which size and power requirements are of particular concern. It is particularly well-suited to designs which require a high voltage, low capacitance capacitor in a very small package. Potential applications include high-frequency switching power converters, DC-DC converters, voltage multipliers, and power supplies, as well as more general electronic applications such as filtering, decoupling, and noise suppression.

Conclusion

Mica and PTFE capacitors remain a cornerstone of electronic design despite advances in other technologies. The CMR06F911FODP capacitor is a small, high-performance example of this type of capacitor, and is suitable for applications including power supplies, DC-DC converters, voltage multipliers, and noise suppression. Its high voltage rating and small size make it a great choice for designers looking for a reliable, high-performance device in a compact, cost-effective package.
